motor synchronise daq

[k-usa]

Hello Everyone ,

          i am looking a solution for my problem :

 - A use AKD driver with Brushless motor

- NI motion 7344 : https://www.ni.com/en-us/support/model.pci-7344.html

- Ni DAQ - PCEI -6363 : https://www.ni.com/en-us/shop/model/pcie-6363.html

I use AKD with the NI motion to drive the motor and , i want measure at same time 4 analog input with PCEI

 I Use this

Hi k-usa,

I would check out the periodic breakpoint example that ships with NI-Motion. You can find it under Hardware Input and Output » Motion Control » NI 73xx » Capture and Compare » Periodic Breakpoint Output.

This will output a digital signal on the 73xx that will match the encoder. You can then put a wire between this output and an input on your device. Finally, configure your DAQmx task to use the input on your 6363 as the sample clock. This will synchronize your measurements with your motor.

Hi k-usa,

Could you probe the error wires on your VI to determine which function is causing the error?
